Subject [jira] Updated: (HADOOP-6723) unchecked exceptions thrown in IPC Connection orphan clients
Date Mon, 26 Apr 2010 02:44:49 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-6723?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Todd Lipcon updated HADOOP-6723:

    Attachment: hadoop-6723.txt

Patch simply catches the exception and closes down the connection. The included test case
times out without this patch, since the call waits forever.

> If the server sends back some malformed data, for example,  receiveResponse() can end
up with an incorrect call ID. Then, when it tries to find it in the calls map, it will end
up with null and throw NPE in receiveResponse. This isn't caught anywhere, so the original
IPC client ends up hanging forever instead of catching an exception. Another example is if
the writable implementation itself throws an unchecked exception or OOME.
> We should catch Throwable in Connection.run() and shut down the connection if we catch
